M250 Ideal Choice for Flat Grinding Small to Medium Parts 500X250mm Worktable Hand-Crank Surface Grinding Machine

The machine bed casting is made of HT250 ductile iron and undergoes natural aging to eliminate internal stress, reduce deformation, and improve machining stability and accuracy.

The ball bearing guideways utilize high-strength ball bearings, which are resistant to deformation. Synchronous belt drive ensures smooth and labor-saving operation of the hand-cranked worktable.

The precision spindle employs a high-precision spindle and P4-grade precision bearings, characterized by low noise, vibration-free operation, high precision, and a high surface finish.

After the guideways are coated with plastic, the contact surfaces are manually scraped to remove impurities and protrusions, reducing wear and extending machine life and improving machining efficiency

The M-series surface grinders are divided into M manual surface grinders, MD electric surface grinders, MY hydraulic surface grinders, and AHD fully automatic surface grinders.

Regardless of whether it's a hand-cranked, electric, or hydraulic surface grinder, the Z-axis is always manually fed. A fully automatic Z-axis feed via PLC is available for automatic grinding.

The M manual surface grinder is a three-axis hand-cranked grinder. The MD electric surface grinder is motor-driven for the X and Y axes, and manually cranked for the Z-axis.

The MY hydraulic surface grinder is hydraulically driven for the X-axis, electrically driven for the Y-axis, and manually cranked for the Z-axis.

The AHD fully automatic surface grinder is available in three types: Z-axis programmed control, two-axis programmed control, and three-axis programmed control. Most require only automatic Z-axis feed.

The grit size, dressing, and operating method of the grinding wheel all affect the grinder's accuracy. It is recommended to grind the chuck first after delivery before proceeding with machining.
